Abstract
A new concept of habitat evaluation procedure for planning and designing the restoration of coastal wetland was discussed. Establishing an independent coastal ecosystem is suggested as a goal of the restoration of coastal nature. Two important concepts were suggested. One is the ecological inter-relations among reed field, tidal flat and seagrass bed. The other is the ecological network among remote coastal wetlands, which is important for the reproduction process of benthos on the larval planktonic stage. Habitat suitability index models for reed, short-necked cram, lugworm and fiddler crab were already developed by authors as the representative organisms of coastal wetland. A basic idea for the model evaluating the ecological relations among these components were presented.
